Patent DE-2908307-A1 (DE)
Title: Instantaneous and mean parameter values - are recorded on single channel listing either larger or smaller value esp. for pen recorder plots
Inventor: LINDNER PETER DIPL PHYS
IPC: G01D1/00
Filed: 1979-03-03
Abstract: A method and device for operating a pen recorder to record a varying parameter and its mean value involves less equipment cost than conventional methods and devices and enable the magnitude and average value to be recorded more suitably for comparison between them. The average and instantaneous values may be displayed in such a way that the mean value is superimposed on the instaneous value. Alternatively, the larger or smaller of the instantaneous and average values may be recorded. Signals corresponding to the instantaneous and mean values are applied to comparator circuit inputs. The comparator circuit operates a switch so that the signal corresp. to the larger or smaller of the instantaneous and mean signals is fed to the recorded input after amplification as appropriate.

Patent DE-3007001-A1 (DE)
Title: Pump for small quantities of liquid - has tubular piezoelectric transducer excited to break seal with cylindrical core
Inventor: HEINZL JOACHIM PROF DR ING
IPC: F04B43/09
Filed: 1980-02-25
Abstract: The pump has a piezoelectric transducer (3) with three separately-excited contact regions (4-6) on its outer surface. The transducer is tubular and encircles a cylindrical core (2). The transducer connects the pump's inlet (7) to its outlet (8). With the transducer unexcited, the core fits tightly inside it and acts as a seal preventing the liquid from passing from inlet to outlet. When the transducer is excited, it expands and produces a gap between it and the core so that liquid can pass through. The advantage lies in avoiding the need for inlet and outlet valves. The pump-effect is achieved when the transducer is deexcited -- liquid between transducer and core is forced towards the outlet.

Abstract: The main constituents of the deformable repair substances are the different materials normally used for effecting repairs, such as rubber, leather and for this purpose pulverised discarded rubber tyres, and other waste scraps of rubber, leather, plastics etc. can be mixed with a suitable two-component adhesive. For a more rapid hardening and better adhesion to the repair spot a second adhesive component can be added immediately prior to use of the substance. For a longer life and resistance to wear solid constituents such as hard granular particles of metal or glass can be mixed in during manufacture of the substance. The substance can have any coloured dye added.

Title: Biological waste water purificn. - with addn. of density-controlled open hollow bodies allowing abrasion-protected bacterial growth
Inventor: SIEPMANN FRIEDRICH WILHELM DIP
IPC: B01J19/30
Filed: 1980-05-07
Abstract: Biological waste water is purified by using solid bodies which are kept in flotation and in constant motion and to which there adheres a bacterial growth. Excess bacterial growth is removed, to leave sufficient growth for purificn. process as a thin bacterial surface layer. Novelty consists in adding open hollow bodies to the waste water-activated sludge mixt. of a standard activation tank, in the presence of O2. Hollow body specific gravity is selected to suit that of mixt. and its flow-form, so that they are driven in flow. Hollow body shape and size is selected so that inside them the bacteria find a growth-surface protected against mechanical abrasion. The process is used esp. for purifying conc. industrial waste waters. The advantages of activated sludge and trickle filter processes are combined in one reaction tank. Microorganisms having different purificn. properties can be cultivated in one activation tank. Easily- and difficultly degradable materials can be decomposed in one working step, including nitrifying and denitrifying of N cpds. Clarifying plant can be restored by hollow body addn.

Title: Matrix display of two pole elements - has selection cycle to avoid cross talk between cells and increase definition
Inventor: BEHRENT HERMANN DIPL ING
IPC: G09G3/38
Filed: 1980-05-09
Abstract: A matrix display system utilises two pole display elements interconnected to minimise external connections and to minimise the possibility of cross-talk between cells. The display definition is increased and the number of elements within a given area is increased. For a 2x2 matrix has element cells (11,12,21,22) formed between the row (Z1) and column (S1) interfaces. The condition of each element depends upon the applied voltage, e.g. the change in one element (11) is produced by a potential difference between (Z1,S1) with the line potential (Z1) being applied to all cells in the row. The selection cycle consists of firstly loading the specific cell and then discharging other cells in the row.

Title: Washing machine having upright drum
Inventor: BOCHAN JOHN
IPC: D06F37/40
Filed: 1980-05-14
Abstract: Washing machine has an upright perforated drum mounted on a vertical axle which can be displaced from the axis of a vertical drive spindle by a horizontal distance (d) considerably smaller than the drum radius. During the washing process the motion of the drum is such that the axis of the drum describes a circle of radius d around the drive spindle, whilst the drum is locked to prevent rotation about its own axis. Liquid is expelled from the load by moving the drum axis into coincidence with that of the drive spindle, where by the drum can be rotated about its axis.

Title: Coupling for articulated vehicles - combines saddle coupling and trailer coupling with trailer coupling pin on horizontal and vertical axis cutting point
Inventor: MOHR MANFRED
IPC: B62D53/06
Filed: 1980-06-27
